Asking in the correct forum will get a better response.Read the RULES!

There’s a big advantage to naming 3 or less replacement properties in regards to 1031 rules.

You can I would just watching to not to apply too many places. 

All the same rules of a standard DSCR cash-out refinance would still apply.

What Schedule can not do is contradict itself and it will always be over-ruled or governed by the LTB.

But I will say that 1031 will not apply, that needs to be a longer-term hold/investment. 1031 applies to rentals, STRs, MTRs that are held for much longer. 

So that rules out areas like City Heights / Skyline / etc.4) Parking - make sure you scope out the parking situation before you buy.

That will meet the 1% rule, but is it realistic in that neighborhood?

While this isn't a hard and fast rule, more often then not, these are the guys that can't manage their schedules well, and will be gung-ho on your job for a couple weeks, then be flaking out as they picked up too much work and are trying to keep too many homeowners happy.And lastly, the more detail you have the better the bid will be with few change orders.  

Just keep the amount within any local rules and give proper notice.
