@Ryan JohnsonI'm new to Houston RE and I've been looking (in HAR and other online MLS) for multifamily properties and I only get like 5 and out of those 5 3 are SFH with a shed on the back they call an apartment. 

I only do smaller parks becaue of its lucrative returns and small capital needed, but since you have more than double that money, you can invest in a stable, bigger park. 

That's a negative but for us not a big problem.When shopping these locks their are basically 2 kinds, those that operate the deadbolt automatically and those that don't. 

I only have one idea that may be accepted by your landlord dependent entirely on your sales from now until the end of your current lease, and the projected sales in 2021 when you sign a new lease.It's called a "Percentage Rent" lease in Commercial Real Estate.

I'm not familiar with your market but after such a long time of being in the negative I'd consider bailing with my bag of cash to invest else where now that you're wiser and with more resources a.k.a BPGood Luck!

There are a lot of variables that will wipe the $150/door out and take your small return to nothing or negative.

At this moment, I only own one apartment in ski report in Alps mountain and want to expand my portfolio.

Since I only make decent money during the summer do you think that would affect me getting a loan?

What if any of these negative scenarios are simply perceived by the other party?

Too much car noise could generate some negative feedback on your rental listing.
