I am in a different market, but be careful. Rental Market is getting a little dangerous. I sold my rentals about 2 years ago.. To fund a business.. I got lucky. Had no idea what was coming.
First.. Everyone is buying again, that alone hurts rentals (not nearly as much in a college town.)
Second.. Too many Rich Dad, Poor Dad's and Lifestyles Unlimited already, now we have every Asian in town using money from the homeland investors. Add in PE funds and the supply of rentals is outpacing demand. There is an apartment boom to boot. There are a dozen houses in my neighborhood for rent... Avg $1750-$2.3k. There are only 3 or 4 for sale for $375-$550k. The old 1% rule (monthly rent is 1% of purchase price) is more like the .5-.7% rule now.
The Asians and PE guys are just parking money until bond rates increase. They don't care about income, bc they have no mortgage interest. Even with management fees, appreciation is good and RE is safe.
Anywho. Check multifamily start permits on the census website if you can. If there is a big bump in multifamily permits in Starkville, that means a lot of apartments are on the way. Check the tax roles and see if you see an abnormal amount of Asian names. If either of these are the case.. sell and take your equity. If you are sure these issues are not coming to Starkville, there are plenty of loans online at higher rates that will let you have lower LTV. Stay away from hard money.
Since you have multiple properties, you should research the portfolio loans. My mortgage guy put me in one and I was at a much better LTV because the risk was spread. Easy to find out west. I had someone tell me that Private Equity groups are quietly trying to get out of rentals and will finance in house for investors buying 5 or more at a time, but that's on the properties they are dumping.. probably the very best sign the rental market is toppy.
I assume you are on biggerpockets.com, but if not you will find more information there than we can ever give.
My advice..
If you have solid remodel skills, don't waste your time on rentals. Sell it. Its a seller's market. Tax advantage will never be better. Yes, there are flippers on every corner, but there are three "passive income" investors on the same corner. Most flippers are trying to do it low risk and fast. Most stay away from the value in older homes because they are scared of something bad.. If you are not, the money can be good.
Rent out new homes with low expenses. Sell the old ones cause **** be breaking.
Knock em dead. I will reach out in 10 years when I need a place for my oldest!
ETA. I wrote this hours ago and just submitted when I hopped back on my phone. Plenty of other good advice and you sound like you know what you are doing.
