You’re trying to ruin the biggest benefit of the life in flip. 

My biggest concern is the basement.

Back yard landscaping is usually the biggest expense at $5-6k for artificial turf and rock, but doing this sets you apart from the others.

I would say the biggest thing I would do is focus on finding bigger cash-flow markets known for great rents and try to see if that works.

one truism I think for rental real estate is returns and price points are very much risk adjusted highest returns lowest price points  biggest risk.. smaller cap or return and prime location least risk..

Hurricane Helene was the biggest flooding event in Tampa bay in over 100yrs just last fall.  

I have a client in KC that has acquired 45 SFRs and is just now looking to buy MF properties.Two of the biggest things to consider when buying a commercial property (5+) versus a 1-4 MF is cost (e.g., the appraisal for 5+ is at least $2k-$3k) and the financing structure by lenders because Fannie/Freddie don't generally buy loans for commercial properties.So, for you personally, the biggest driver for the type of your next property is probably going to be the amount of a down payment/equity you can put in the property.

I'm also concerned older homes have already seen their biggest jump in capital appreciation and don't have as much potential for price growth compared to newer homes.What are your thoughts on older homes?

Coin jams are going to be your second biggest headache unless you invest in those fancy ones with tap-to-pay but those cost a pretty penny.

Do number, size, or area of investments owned play the biggest role in that decision?
