There are no easy fixes.  

Since you know who you want to serve, try to tailor your listing to make it easy for them to say, "yes".General advice: MTRs are attactive to a lot of people because of the increased cash flow, but it's the appreciation over time that really generates wealth in real estate.

DCSR loans are easy from a qualification prospective but depending on the market your may need a larger downpayment to make the DCSR ratio work. 

I am also a realtor which has helped me in the sense it makes it easy to see houses.

The short answer to your question is that the general rule is one year.

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

There are many hard money lenders who do DSCR with less ins and outs and less rules.

3) Dealing with Contractors: guess you found it's not as easy as the "gurus" make it out to be. 4) S8 slightly above.guarateed Rents: typical naive mistake.

If this is a problem tenant who continues breaking rules, that's something you can work on later but for right now you should do the right thing and look into this.

It should be as easy as converting one conventional loan that cashflows well to a Debt Service Coverage Ratio loan or DSCR.
