Surprisingly I think I like the SFR, (lower maintenance costs and tenant interactions per cash flow dollars).

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. 

Ultimately you have to figure out your budget and then decide what particular methods you can afford to pursue at the moment.  

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

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.

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

For Buy and Hold strategies, this method is far more superior than traditional financing of properties.

Costs for these services can vary by region and lender.

Or, are you trying to fund buying a property + construction, and then cash-out-refinance the completed project to pull back out most of your purchase + construction costs to deploy on the next project?
