I'll share since you're also my electrician.
FB Marketplace. Going to get a ton of tire kickers but it can be nice to see the profiles of who you're talking to. One thing I always check is their own marketplace listings. If it looks like their main job is peddling used shoes on FB, that's a no go. If they have bad reviews from others about their marketplace dealings, that's a no go. People will post all kinds of stuff to give you reasons to pass them up. If their friends all look like they just got out of prison or they've friended a bunch of pit bull rescues, dont even respond.
FB also has a few Aggieland groups for people looking for rentals. Ive had a little luck on those. It's mostly used by students, if that's your property type. But it can be weird. Most of the postings seem to be scantily clad college girls looking for roommates on properties they already leased. Seems scamy but the pics usually show that they're actually Aggies. People often even call them out in the comments about why they feel the need to show slooty pics when looking for a roommate. Sign of the times I guess.
Zillow. It cross post your listing to trulia and hotpads. You can put in your minimum criteria. Itll tell you if people match but wont keep the others from contacting you. Their email and messaging system does a good job of organizing messages and helping you to keep up. For some reason, just in the last month, scammers have started hitting their messaging system acting like zillow. Be very cautious of any message that doesnt appear to be an actual tenant. Ive never gotten a legit message from zillow.
Bonus tips. Put all your minimum requirements in your listings. Credit score, maximum number of occupants, income requirements, needed move in date, etc. If you plan to allow pets, just say pets are on a case by case basis. Then ask people what pets they have. If you put down what types or how many dogs you allow, people will lie because they know it's hard for you to verify. They tend to not lie about credit score, income, etc because you can verify that. Be ready for people to tell you every pet they have is a service animal. These are experienced renters that know the system. Not saying dont rent to them but be cautious.
Ask a lot of questions up front. Im sure I run some people off by pestering them up front but I probably dont want to rent to them anyways. Before scheduling, ask about all the same things you put in your listing requirements. Credit score, income, how many total people living there, needed move in date, etc. This will eliminate 85% of the showings that were never going to work out. You can put down that the place is available for June 1st move in and you're going to get 100 people that will message you about how much they love the place and its perfect and they want to schedule a showing ASAP. Then when you ask when they want to move in, they say August 1st. Huge time suck to show the place to those people. If I had to put a number on it, Im showing an average of only 2-3 times to get a lease on a non-student house. The worst from a time standpoint are the college age females. They qualify for the property so theyre hard to weed through up front. BUT they are terrible about shopping for that PERFECT place. Some of them must look at 20 places before deciding. Act like they're going to be living there for the next 30 years.
Take lots of good pics. Id say a minimum of 15, preferably 20. Dont be afraid to show the bad aspects of a house up front. It will save you time later. Lots of people forget good pics of the back yard, parking, etc. Good pics get you views. Good pics also eliminate bad showings.
