A letter from you highlighting the positive features of the new home you find attractive (bigger yard for my dog, another bathroom for my teenager, etc), paired with evidence that you did in fact historically owner occupy for a year (old utility bills, old mortgage statements, old paystubs, etc, addressed to your then-current residence work), would make it pretty rock solid, but this is still ultimately an underwriter judgement call.Because preapprovals are not property specific, they can never incorporate this, so it's on you to set yourself up for success on this front.

.- That part is usually actually pretty easy to overcome, for the reasons you highlight pertaining to neighborhood, etc.

I also highlight the fact that because it is the off-season, they will completely avoid the tourist-y, crowded days.Those are just some ideas

Send her a copy of the lease with that section highlighted 

This list includes the top 10 U.S. cities with the highest rent growth (by percentage) over the course of five years and highlights their struggle and success.

I would first send a statement of charges to the tenant (via certified mail), highlighting the rent shortages each month.  

It could include two things: highlights of the most important landlord/tenant practises/laws and perhaps an appendix with a quick how-to-guide for the most common issues.

My calculations above highlight that fact that to pay off the mortgage early (or pay all cash, or use 15 yr mortgages)....a portion of your precious capital is making the 4.5% yield (the APR of your mortgage).Have you considered using the BRRRR method (I'm a big fan).

Some highlights- ConC return 22%- Net Return 10.99%- Rents are $150-$200 below market- Valuation based on 8% cap rate $630K.

What are some of the highlights, and issues that you dealt with in your early days of investment that are just not problems in the market anymore?
