There is a very strong effort to ban them completely from R1 zoned areas which has made it very difficult to apply for a permit unless you buy a house which currently has a permit in place.

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. 

Sure, you can apply a huge contingency to anything as a safeguard but that won’t help you win many deals.

How do I know if this applies to the areas I'm looking at?

Last questions, can't a voucher holder apply to any home of any size in their approved area? 

There is no chance home owner can mediate, apply for loan modification (which is a predatory disaster in itself) , reinstate or retain the home two days before auction, when they have zero funds and ability to do it.

I'm going to see where I can apply my knowledge I'm still a young padowon haha

DSCR has other guidelines, but generally the same rules will apply more or less.

My concern is that if i apply for a HELOC to use for the down payment before i apply for a mortgage, A) I wont get approved due to my DTI ratio, and B) I wont get approved without first showing the bank I have the 20% down payment before pulling the HELOC.

Hence, the decision was to make the flight using a single-engine plane.The same logic applies to multi-family properties: a fourplex has four times the vacancy risk of a single-family.
