You shouldn't be having DTI issues provided you are buying good cashflowing properties, overlays pertaining to the "counting" of rental income is likely what is at play.

However, the part of rent control that pertains to asking them to move out when the lease is over still applies.

I highly recommend you consult with a knowledgeable CPA in the area of international/cross-border taxation especially as it pertains to estate taxes.You are correct - a nonresident alien is generally subject to an estate tax on their U.S. situs assets of 40% on the excess of $60,000.

@Michael Noto"From experience, even if the tenant is in the wrong do you think they have $10k or even $5k laying around to pay"That statement, pertaining to whether you charge the tenant, is irrelevant.

However, in the context of an acquisition cost or contract price as it pertains to lending risk, what is ARV? 

They have documents pertaining to the house as well as instructions for who can bid, when, etc.

While it may not mention anything specific about STRs, there could be another provision in there that would actually pertain to it somehow. 

A friend is looking to purchase a vacant lot for around 10k however it has over 150k worth of liens City of NMB code enforcement (the liens   were placed on a bulk of lots since the previous owner never kept up the lots).From what we read in the title report the actual liens pertaining to the property is only around 6k however the "bulk" lien placed on all vacant lots is around 150k.Anyone ever deal with this before?

But I do have a few questions pertaining to Lease Option Agreements.Can I use the same “Lease Option Agreement” for both sides of the “seller/me” and “buyer/me” , and just change the terms?

Good to consider the seller's needs here as it pertains to their tax and estate planning needs.
