You have to get someone to walk it, give you a reno cost, then inspection and appraisal , takes time, Good luck 

Legal remedies can get costly.

Some lenders will require as little as 15-20% down (of the total project costs.) 

Loans from the FHA, online investment groups, middlemen, rent-to-buy deals, ready-to-rent homes, and borrowing from private lenders can cost less at the start, grow in value, and give you a steady flow of money.

First flips cost twice as much as you think and take twice as long, every time.

There's preferences.If i have to choose, I would choose either AppFolio or Yardi Voyager, but these can cost anywhere from $14K to $150K. 

I keep hearing how people are cost segregating, but I have pushed my accountant numerous times on this and he just saying that if we did the cost seg, all of that depreciation would just go into a reserve that would then be applied when we sell the home. 

Also run a few scenarios of costs and see how much over budget these repairs can go before you don’t think it would be a good deal anymore.

The property will still cash flow with the extra cost of these expenses. 

I give the warning because these tenants live in a little bubble and aren't considering the costs and inconvenience of moving.
