If you are deadset on refinancing into a conventional loan, then you will likely run into seasoning issues.

@Bryan HartlenManaging low-end properties can be demanding due to higher tenant turnover, increased maintenance needs, and frequent rent collection issues.

A lot of the top places have seasonality issues so don't let it scare you.

If I had an answer to my money issue then I would quickly pull the trigger on a good deal. 

@Kayla Elliott  Hi Kayla - this was a commercial mortgage loan with a local bank, that held it "in house" after it was issued. 

The buyers did a long inspection, multiple days... made a huge request for concessions based on what we knew to be purely made-up issues.

Managing a property hours away can be challenging if any issues arise, but having a third-party property management company could help handle those situations and make things more manageable.I think you are in the right place to gain some insight on what would make you successful.

I think the engineering issues on them have been resolved.I've used a number of different brands (lower price point) and haven't had issues with any of them.

Hiring someone to do the work will likely cost too much (I would charge a small fortune, it's an incredible amount of work) and doing things as cheaply as possible will bite you in the *** later when you start having issues with your own shoddy work and/or materials.
