Hello all,  I am looking for advice on management software to help manage a MHP.  

What if a few years down the road the seller runs afoul of the IRS and they file a lien against all of his assets.

@Nicholas GrayResidential rental property is depreciated over the mid-month convention.The software appears to be calculating it correctly.There is no election to use the mid-year election.

I have a similar strategy for stock trading, but it's extremely expensive and difficult to make a software for the scale that ill be using it for.

Find asset-based lenders who can do permanent loans. 

The reason these things matter is because they help you determine the value-add amenities/potential for your asset. 

If it's a marginal deal and you have little to no experience you should probably just fix your credit.The money also has to come from their funds sourced from their asset statements over the last 60 days in order to get approved by the lender.

If you are accumulating then refinance is a great way to have higher asset base to work with and more opportunities.

I was intrigued by the topic of "opportunity zones" discussed on the BP Podcast episode 269 (the one about RE & taxes).As I understand it, it seems almost like a "1031 exchange" type of investment vehicle but rather than property<>property, you could use other equity assets like stocks or mutual funds to invest in designated opportunity zones in low income neighborhoods via opportunity zone funds.

As for DTI, with only 1 house it's hard to have a DTI that's too high, as long as you're below 35% you should be fine, if you get near that then you'll need a mortgage broker to break out the complicated software that give you a real DTI number which is more complicated than debt payment/paycheck.
