The bad thing about these issues is they are costly.

I keep reading that it will be so hard to seperate the costs for each unit.

Let's work together to change the game for the mutual growth of your REAL ESTATE business.

So, yes, you can absolutely get a traditional loan using 20% down an receive a loan with lower closing costs and a lower interest rate...or you could go the other route.Hope that makes sense how I am describing it. 

If cabinets are in excellent shape, leave them alone.Accent wall adds no value.Would need photo and layout of existing bath and proposed bath and total rehab cost to tell you what value it adds, my guess is it adds $5000 in value or less.

The only negatives with an assumable loan is that they take longer to close, 60-90 days generally, and you would also need to come to the table with a little cash to cover the sellers equity (if any) and some other closing costs. 

Didn't have much cash on hand but wanted to get in the game!

And unless they're damaging the unit, I don't think I would go so far as to evict them for not paying the deposit, it will end up costing you more.What you might be able to do (check with an attorney) is charge them a late fee for not paying the deposit.

I saved on buyer-side closing costs by representing myself.

It may be possible for a UPS Store to print it and have them pick it up to save on shipping costs?
