Do you have unusual expenses for that property such as very high taxes, HOA, etc?

It is not unusual to see rent to price ratios below 0.5%. 

I've been doing infill lot's in PG county Marland and the process I can tell you differs from county to county but I'll give you an outline of my process 1) It's not unusual to see lot's on the MLS for 100+ days, do not be alarmed there are not too many people operating in the sphere 2) Just like rehabs I typically start by looking at what I can potentially build on the lot and my ARV  ( I know my area pretty well, so I'm only buying lot's in specific zipcodes ) my typical target is 2500sqft above grade with an AVR for $500+ 3) My research starts with my surveyor, I provide him with the address, he comes back to give me thumb-up or down or any potential problems I may face, such as wetland, DDO zone  (Development District Overlay) e.t.c 4) After closing on the lot in my county I need to get NRI ( Natural Resource inventory) this plan provides documentation of the existing conditions on a site / TCP ( Tree Conservation Plan ) exemption, I get an exemption because I'm buying infill lot, this is typically handled by my surveyor and take about 30days 5) Next is my stormwater management: Again I'm getting an exemption because I'm disturbing less than 500sqft of land, handled by my surveyor 6) Once I have the 2 approvals listed above, I'm allowed to submit my building plans for approval, in my county turn around time for approval is about 3-4months Hope this helpsbelow is a link to my last new construction project, got a few more in the pipelinehttps://www.redfin.com/MD/Cheverly/2417-Parkway-20785/home/10547525

I have yet to find the path beyond the following obstacle:My rental property's post-hurricane-damage repair costs (beyond insurance payout) resulted in large expense deductions and an unusually low taxable income. 

From the Limited Partner (LP) perspective, you will not realize the difference or have any unusual tax work on your side required.

That is not unusual but there are variations here: one month's rent charged to change tenants, another without that charge but $400 to set up your account initially. 

They have about 5 years of these lines and total about $50k including penalties. last sale of the home was in 2016 and listed in the county records as $0 and the Condition of Sale listed as Other Unusual Factors.
