Additionally, I am prepared to offer either a first position on the loan or cross-collateralize with my portfolio of seven vacation rentals, valued at approximately $12 million, with $6.5 million in available equity and generating $1.4 million annually in gross rents.Given the potential of this project, combined with my experience and the collateral available, I seek advice on approaching potential lenders or investors and effectively negotiating terms within such tight time constraints.

Here's a generic bid sheet for a basement finishing project.

Our biggest pain point was buying a home that needed significant renovations that took too long.

We can buy properties cheap enough that a lot of lenders don't want to mess with the small sized loans.Hi Darrin,I recently purchased a property cash that will need some renovations.

For newly constructed, purchased or renovated properties and also retroactive generally over the last 10 years, building components are properly classified into individual units of property and accurate recovery periods for computing depreciation deductions.

Required re-zoning and addition of 2 residential bathrooms and complete renovation of kitchen.

With the proof of the other side being completely renovated, it seems like that would be the best comp to have as a reference for what is possible with the unit I am looking at, and it looks to me like it should be a good investment.

but it sounds like you know a lot of what you DON'T want; what you do want is the opposite. if you're going to do your next project alone, it sounds like you want a LTR nearby that's relatively turnkey without any problem-tenants. you can do a 'lazy 1031' where you just sell traditionally & in the same calendar year buy the new property, while working with your cpa to figure out how to offset the tax bill. you could alternatively partner with an active investor on your next deal; that way you could invest in what could be a higher cashflow market compared to where you live, and not have to invest much time (since it sounds like you guys don't have as much time to spend on this now). 

Property plan is to bring rents up to market rates with renovation and neighborhood upgrades over a 3 year period, expecting ~8% dividend yields, and capital return in year 3.

While it might seem like a significant upfront cost, properly addressing these issues now can save you from more expensive and complicated repairs down the line.Best of luck with your trailer house project, Emmitt!
