You will need to supply 2-3 quotes from different General Contractor's or licensed builder for all work.Some things that can occur are builder/vendor issues with lack of inventory, broken material, employee "no shows", date of completed work extensions, bad work, additional costs not factored on blue prints or cost analysis, delayed permits.Keep in mind any delays or issues will slow down your clear to close/funding date.

The market here is extremely difficult to enter due to cash offers and low inventory.

You would be looking at a rate in the low 8s based on your credit score. 

If you can definitively prove that the seller intended to deceive you about the square footage for their personal gain, you may be able to take legal action, but probably low chance of success considering you had ample opportunity to measure the home or get an appraisal with measurements prior to closing, and had your chance to negotiate the price based on square footage and all other factors prior to closing. 

The reason why is in a fund your money is always working 12 months out of the year.

Even if you get nothing, you are helping out your fellow landlords by getting it on record that they are low life tenants. 

The first unit has ~75% occupancy but mostly because I take it off for a few weeks in low season to go through everything, fresh paint, etc.  

While still technically in seller’s market territory, inventory is well above extreme lows seen in recent years and has held steady for many months now.

That trend stopped after the 70's but manufactured housing was a major contributor towards creating stable affordable housing.If we want to tackle our housing shortage we need to get serious about it.Here is a quick summary of the HUD changes: HUD Actions for Manufactured Homes and Communities:HUD announces a comprehensive set of actions to increase availability and affordability of manufactured homes.These actions are part of the Biden-Harris Administration's Housing Supply Action Plan.Manufactured housing is a key component in the strategy to boost housing supply and reduce costs.Preservation and Reinvestment Initiative for Community Enhancement (PRICE) Program:HUD launches the PRICE Program, a $225 million competitive grant opportunity.The program aims to preserve and revitalize manufactured housing and communities.Funding supports repairs, rehabilitation, replacement of units, infrastructure upgrades, and community resilience.Available to states, local jurisdictions, tribes, nonprofits, community development finance institutions, and other eligible entities.FHA Draft Policy for Manufactured Home Communities:FHA posts a draft policy to solicit public feedback.The policy aims to promote stability and affordability for individuals and families in existing manufactured home communities.Allows resident-owned cooperatives and mission-oriented borrowers to access FHA-insured financing for purchasing or refinancing.Updates to FHA's Title I Manufactured Home Loan Program:HUD announces updates to FHA's Title I Manufactured Home Loan Program.New methodologies for calculating loan limits to align with current market pricing.Expects the new loan limits to incentivize more lenders to participate and expand program usage by buyers of manufactured housing.Annual Recalculation of Title I Loan Program Limits:FHA will recalculate Title I loan limits annually to keep pace with home price changes over time.This ensures that the loan limits remain aligned with market conditions.Ginnie Mae's Title I Loan Securitization Program:Ginnie Mae takes steps to reinvigorate its Title I Loan Securitization program.Revisions to financial eligibility requirements for Title I Issuers to reduce barriers and increase lender participation.HUD's Ongoing Support for Manufactured Housing:These actions build on HUD's continuous efforts to support manufactured housing.Earlier actions include a proposed rule for the Community Development Block Grant (CDBG) program emphasizing the needs of manufactured housing communities.Recent Updates to CDBG Notice:HUD updated the CDBG in Support of Housing Activities notice to allow the use of funds for acquisition of manufactured housing units, services to homeowners, and investments in infrastructure and resilience for manufactured housing communities.

@Michael MastersTo answer your question directly, you could do an installment sale where you receive the funds across two tax years...Just to be sure since many people mess this up:  you figured your profit as your net sales minus your cost basis (basically your purchase price plus your capital improvements), correct?
