If there are low-cost (both time and money) ways of achieving this, such as filing a complaints, it may be worth it to put on your resume so you can tell awesome stories like @Jay Hinrichs', but other than that, it's just spite.

Naturally we would try to stop our kids from making excessive noise but of course they would resume not too long after that. 

I would find a local builder there that you like, know, and trust and is well known for the area with a full resume full of recommendations and happy home owners.  

We are currently in a Seller’s market so prices will likely resume their climb should this low inventory trend persist.

I mailed my resume and a cover letter to some experienced sponsors.

I understand the reason for the percentage you set aside for maintenance or vacancy, but wouldn’t you stop putting money into that after a certain point and resume after you had to dip in those funds?

If you really want to get involved send people like me your resume and try to work for them.

HI LIsa,It sounds like you dont want to do a full doc loan yet you’re running into full doc lenders, perhaps lenders who have stated/no income/bridge/HML programs but they dont know how or dont want to use them.If you do chose to go the less income or less documentation routes you’ll have higher rates and cost.It just depends on what your game plan is for this property.If you only need “50k to avoid bleeding out financially” then I would recommend to get a HELOC on another property, 401k loan from your 401k up to 50k, card advance (nuclear option), use bridge or refi into another hard money loan (last nuclear option), or if you have enough income refinance utilizing conventional with full doc as that will be permanent term financing and typically the lowest rate or best execution given the situation you have mentioned above.
