I'm not a lender so this isn't exactly my lane (feel free to check me here @Andrew Postell) — I believe Fannie/Freddy updated their seasoning requirements on refinances from 6 months to 12 months, so you would have to bake that timeline and holding costs into your total budget and project plan.

Taking you time allows you to bake mistakes slowly and learn for the next one.

You need to negotiate and bake banana bread for neighbors before you pay an architect if you dream of adding units to an established old golf course neighborhood.

Let's say both the properties are freshly renovated.In general... is it safe to say the 3BR house will rent for 1+k/month MORE than the townhouse even though the townhouse has nice views and is a smaller in size?

He probably has some really fresh insights.

Something durable but light and simple to keep the focus on the moutains :) We are in a stange place as a society, tourism lost is freshness and speed but we are confident that some people will soon want to have the opporunity to sit, walk and relax in a place like this one we have in our heads.And if this project hatches and lives well, we would like to build the same type of "house" on another land that as the same type of criteria, beauty, calm, nature and some tourism.You toughts would be appreciated, have you any ideas on this topic (building short term rentals)?

@Alan FordWhile $1200/month NET profit looks very impressive, once you bake in depreciation over 27.5 years, the real profit becomes less desirable...sorry to be so blunt....

At that time, we got fresh leases from both tenants and decided it was time to sell the property.

Have them remove all the shingles and start fresh.
